PORTABLE MELTING APPARATUS.-

SPECIFICATION forming part of Letters Patent No. 721,808, dated March 3,1903.

7 Application filed November 5, 1902. Serial No. 130,137. (No model.)

To all whom. it may concern:

Be it known that I, NEWELL SILL J ENKINs, a citizen of the United Statesof America, residing at Dresden, in the Kingdom of Saxony, GermanEmpire, have invented certain new and useful Improvements in PortableMelting Apparatus; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in portable melting apparatus,and has for its object to provide an improvedsupport for theladle-handle and to so construct the muffle as to facilitate the gradualcooling down of the melted contents of the ladle before the ladle isremoved from the muffle.

In United States Patent No. 653,007, dated July 3, 1900, is shown anapparatus to which the improvements which form the subject of thisapplication may be applied. Such apparatus described and illustrated insaid United States Patent consists of a muffle lined inside withasbestos, open at the front, and provided at its bottom with a hole..Combined with the above apparatus is a gasburner positioned beneath themuffle. The flame from the burner will be directed against the bottom ofa ladle supported within the muffle, passing through the hole in thebottom of the muffle.

Instead of having the bracket which supports the ladle-handle pivotallysecured to the muffle itself, as shown in said patent, or upon the samepost upon which the muffle is mounted, as shown in United States PatentNo. 585,442, dated June 29, 1897, which are objectionable, the onebecause it cannot be turned to a position in front of the opening in themuffle and the other because it cannot be adjusted vertically relativeto the muffle,

up end to prevent the ladle-handle from accidentally slipping off. Whenthus mounted, it can be adjusted vertically or laterally relative to themuffle, as desired, and can be turned to position directly in front ofthe ladle-opening in muffle.

The drawing shows a perspective view of my improved apparatus.

In said drawing, A represents the muflfle,

which is supported upon a suitable post B,

upon which it is adjustable vertically and upon which it may be turnedlaterally to suit the con venience of the operator. It is adapted to beheld in position by a set-screw G, passing through a collar attached tothe muffie and through which the supporting-post B passes. The muffle isprovided with a hole D in the bottom and a side'opening E for theintroduction of a ladle containing the substance to be melted. Below themuffle is the burner G, pipes H, which supply the burner with fuel, theregulating-scalel, and the regulating-valve J. These parts may besubstantially the same as in said abovementioned patents.

My improved muffle is provided with a centrally-positioned opening K inthe top,which allows the escape of the hot air and gases, so that whenthe flame is turned off the muffle and contents of the ladle will cooloff gradually, but more quickly than otherwise.

My improved support for the ladle-handle consists of a long arm L, acollar M, adapted to go on over the end of the burner, a setscrew N, andthe handle-rest proper, O. For convenience the rest 0 has the end turnedup, as seen at P, to prevent the handle from slipping. The support isadjustable vertically on the burner and is held against accidentalrotation and vertical movement by means of said set-screw.

Having thus described my invention and its use, I claim- 1. In aportable melting. apparatus, a suitable base, a vertical post mountedthereon, a muffle of refractory material mounted upon said post andprovided with a ladle-opening in the side and a hole in the bottom, aburner vertically mounted upon said base below said muffle, means forsupplying fuel to said burner and a ladle-handle support pivotallyzontal and vertical adjustment relative thereto, said support consistingof a collar surrounding said burner, a long horizontal arm and atransversely-disposed handle-rest having handle-guards at the endthereof.

In testimony whereof I aifix my signature, in presence of two Witnesses,this 1st day of October, 1902.
